To Stand or Not to Stand?In 2016, Vallecito Elementary School in San Rafael, California, became the first U.S. school to replace all of its ordinary desks with raised desks that students stand at. Speaking to a reporter from TIME for Kids magazine, one student at the school gave the standing desks high praise. "You feel happier, you're less tired, and you're more active," she said.
